I don't. A guy like Boogaard for example can just cheap shot who ever he wants, because he usually don't have to be "afraid" figthing. And I don't think that's an excuse.
I'm not aware of blindside hits to the head involving Fleming. I know about the buttend and the stick swinging though. Please elaborate.
I do not advocate players playing the game without helmets - I suspect bare heads hitting the ice or being hit by pucks or fists were the primary cause of most long term brain dammage to hockey players, not checks to the head. Again though, I am in favor of a rule calling out headhunting for what it is, unsportsmanlike and dirty.
Cheap shots should always be punished with suspensions. This is ice-hockey, not last man standing wrestling or something like that. The refs and the league is there to take care of the punishments. No team should be having to do that themselves. No team should be having to whitstand cheap shots just because they don't have a guy who takes care that "justice" happens.
